Not Your Usual FFT: QFT$\rightarrow$FFT via Classical Quantum-Circuit Simulation
Stefano Markidis, Gilbert Netzer, Luca Pennati +2 more·Jun 17, 2026
We introduce QFT$\rightarrow$FFT, a family of HPC FFT libraries that compute the discrete Fourier transform by executing a quantum Fourier transform (QFT) circuit on classical quantum computer simulators. Input arrays are mapped directly to state amp...
Nanoscale memristive devices: Threats and solutions
Amir M. Hajisadeghi, Javad Talafy, Hamid R. Zarandi·Jun 17, 2026
Due to their incentivizing features, memristors are a promising candidate for replacing CMOS-based memories, which are faced with various functional challenges in deep submicron process technologies. Memristors are nonvolatile, have low leakage, and ...
Emergence of Resonating Valence-Bond Correlations in Stretched Graphene
Sam Azadi, A. Principi, T. D. Kühne +1 more·Jun 17, 2026
Electronic correlations in graphene are generally considered weak due to the large bandwidth of its $π$ electrons. Here we show that tensile expansion of the honeycomb lattice provides a direct route to enhancing correlation effects. Using variationa...
Exceptional-Point-Anchored Variational Quantum Eigensolver for Non-Hermitian Many-Body Phase Diagrams: Bridging Skin-Effect Topology and Entanglement Criticality on NISQ Hardware
Akoramurthy B, Surendiran B, Xiaochun Cheng·Jun 17, 2026
We introduce the Biorthogonal Variational Quantum Eigensolver (B-VQE), a quantum algorithm for simulating non-Hermitian many-body systems on noisy intermediate-scale quantum (NISQ) hardware. Non-Hermitian quantum matter exhibits exceptional points, p...
Benchmark of Pauli Correlation Encoding for different optimisation problems
Fernando Alonso, Colomán Samprón, Jacobo Veiga +2 more·Jun 17, 2026
The continuous progress of quantum technologies has spurred the exploration of their potential applications across diverse fields, particularly in combinatorial optimisation. In this work, we study a quantum-classical optimisation framework based on ...
Sensitive endoscopic diamond magnetometer for non-contact sensing in confined environments
Johannes Wesseler, Roland Nagy·Jun 17, 2026
Transitioning quantum magnetometry from laboratory environments to real-world applications has been limited by a persistent trade-off between sensor miniaturization and magnetic sensitivity. While bulky systems can achieve high sensitivity, endoscopi...
Field Demonstration of a Multi-User Continuous-Variable Quantum Access Network for Quantum-to-the-Home
Junpeng Zhang, Xu Liu, Qijun Zhang +12 more·Jun 17, 2026
Realizing scalable Quantum-to-the-Home (QTTH) faces a bottleneck: link asymmetry in broadcast continuous-variable quantum access networks (CV-QANs) hinders the selection of a globally optimal modulation variance. We demonstrate a downstream broadcast...
Classical dissipative search of unstructured database
A. E. Allahverdyan, Y. Bisharyan·Jun 17, 2026
We propose a physical realization of the unstructured database search that works via classical, dissipative model of spherical spins. The database is implemented via spin-spin couplings, where the selected coupling refers to a larger ferromagnetic in...
SwitchBraidNet: Quantisation-Aware Lightweight Architecture for Hybrid Brain-Computer Interface
Gourav Siddhad, Yogesh Kumar Meena·Jun 17, 2026
Hybrid brain-computer interfaces (BCIs) that integrate motor imagery (MI) and steady-state visual evoked potentials (SSVEP) provide high-dimensional neural decoding but typically exceed the computational limits of embedded hardware. To address this, ...

Hai-Tao Dong, Meng-Long Song, Si-Yu Zhang +3 more·Jun 17, 2026
The photon blockade (PB) effect is a hallmark non-classical phenomenon in quantum optics and finds important applications for building quantum sources, while the control of PB by the non-Hermitian exceptional points remains largely unexplored. In thi...
